Lovato DM3T0600 solid-core current transformer with a 600/5 A transformation ratio, 30 mm cable opening, 5 VA class 0.5 burden and 10 VA class 1 burden for electrical current measurement.
£36.58
The Lovato DM3T0600 is a dependable solid-core current transformer designed for accurate current measurement in industrial switchboards, electrical distribution panels and energy-monitoring systems. Featuring a 600/5 A transformation ratio, it converts a primary current of up to 600 A into a standard 5 A secondary output for connection to compatible energy meters, ammeters, multifunction measuring instruments and power analysers.
Its solid-core construction provides a secure and durable measuring solution for new electrical installations where the primary conductor can be routed through the transformer during panel assembly. The DM3T0600 accommodates round cables up to 30 mm in diameter and rectangular busbars measuring 40 × 10 mm, 30 × 20 mm or 25 × 25 mm, providing installation flexibility across a range of switchgear and control-panel configurations.
Operating at 50–60 Hz, the transformer provides a burden of 5 VA at accuracy class 0.5 and 10 VA at accuracy class 1. Its compact housing and robust construction support reliable long-term current measurement in commercial and industrial power-distribution applications.
Current transformers provide a safe method of measuring high electrical currents by converting the primary current into a proportional lower-current output for compatible instrumentation. The Lovato DM3T0600 converts a primary current of up to 600 A into a standard 5 A secondary signal, allowing meters and monitoring devices to measure electrical loads without being connected directly to the high-current circuit.
The solid-core construction is particularly suitable for new switchboard and control-panel assemblies. During installation, the cable or busbar is passed through the transformer opening before the primary circuit is connected. This creates a secure arrangement for continuous energy measurement, electrical load monitoring and power-system analysis.

The DM3T0600 is used to measure electrical currents in switchboards, distribution panels and energy-monitoring systems. It converts a primary current of up to 600 A into a standard 5 A secondary output.
The current transformer has a 600/5 A transformation ratio, meaning that a nominal primary current of 600 A corresponds to a 5 A secondary current.
The transformer accommodates a round cable with a maximum diameter of approximately 30 mm.
The transformer is suitable for rectangular busbars measuring 40 × 10 mm, 30 × 20 mm or 25 × 25 mm.
No. The DM3T0600 has a solid-core construction, so the conductor must be disconnected or passed through the transformer during panel assembly. A split-core transformer is more suitable when an existing conductor cannot be removed.
Lovato Electric current transformers are widely used by panel builders, electrical contractors and industrial engineers to provide accurate current measurement, straightforward installation and dependable integration with modern electrical monitoring equipment.
